Dangerous goods officers and freight forwarders rely on hazardous cargo packing instructions to determine which materials, container types, and closure systems are permitted for a specific dangerous substance. These instructions form an integral part of the governing regulatory frameworks — IATA DGR for air, IMDG Code for sea, ADR for road, and RID for rail — and are legally binding. They account for the hazard class and packing group of the substance, as well as physical and chemical reaction risks that may arise during transit. Selecting the wrong packaging not only leads to shipment rejection but can also result in significant liability in the event of an incident.
